The new Dispermax adjuvant, consisting of stabilizers and surfactants indicated for aerial or terrestrial leaf applications, has been announced. The manufacturer, Agrotechnica Soluções Agrícolas, emphasizes that the product, due to the characteristics of its additives, has a specific action on water insoluble particles (suspensions) that facilitate the removal of the decanted solids in the spray syrup - which avoids problems in the spray equipment.

"We have already tested a number of similar products, none of which have shown the same mechanism of action as Dispermax, and have not solved the problem of accumulation of solids at the bottom of the tanks," said Renan Yoshida who responsible for the company's research and development.

According to Yoshida, a great differential is found in the performance in the interaction between the particles of the defensive, without modifying their chemical structure, or preserving the efficiency of the products used. "In addition, because it does not allow incrustation in the equipment, it improves the time for the producer and reduces the generation of waste in the sprayer," Yoshida said.

As a specific adjuvant, the Dispermax, in addition to assisting the homogenization (mixing) of the syrup, provides the maximum use of the active without interfering in the ideal pH of the application. "The formulation of more stable syrups results in a more homogenous and safe application, taking advantage of the potential of active molecules. The result is greater control of pests and diseases and, consequently, more productivity gains and quality in farming," Yoshida noted.

According to Yoshida, the product has applications of water-insoluble (SC), wettable powder (WP) and dispersible granules (WG). He explains that the company is focusing mainly on applications in syrup containing the active ingredient mancozeb, in view of the problem it presents for the applicators in the field and the volume of product used, especially in the soybean crop.

Other active ingredients have been recently tested by the company, such as copper-based protective fungicides, as well as copper oxychloride and copper hydroxide, along with flumioxazine and saflufenacil herbicides. "In all these cases, the results were very satisfactory", noted Yoshida.
